In water safety planning, an infection preventionist's role includes performing what assessment specific to water exposures?

• A. Environmental risk assessment
• B. Infection control risk assessment for water exposures
• C. Safety hazard assessment
• D. Water consumption risk assessment

Answer: (B)

In water safety planning, the key task is an infection control risk assessment for water exposures. This focuses on how water-related factors can introduce or spread infections, and it guides the controls you put in place to protect patients and staff.

Think about how people interact with water systems in healthcare settings—through showers, faucets, humidifiers, cooling towers, dialysis water, and even nebulizers. Water can harbor pathogens like Legionella, Pseudomonas, and other organisms, especially if biofilms form or disinfectant levels drop. An infection control–focused assessment evaluates where exposure can occur (inhalation of aerosols, splash, ingestion, or skin contact), identifies high-risk scenarios and populations, and reviews current controls such as water temperature management, residual disinfectant levels, flushing regimes, filtration, maintenance practices, and surveillance for waterborne infections. It also drives plans for remediation if risks are found and ties these controls to infection prevention goals.

Other types of assessments—while important—cover broader or different areas. An environmental risk assessment is more general and may not target infection transmission from water; a safety hazard assessment looks at physical or chemical hazards broadly; a water consumption risk assessment centers on ingestion risk rather than infection from exposure to water systems. The infection control–focused water exposure assessment directly aligns with preventing waterborne infections in care settings.
